500+ hp Stellantis 'Hurricane' I6 previews a world without Hemis

After years of rumored development, Stellantis has revealed its new six-cylinder engine family. The 3.0-liter, twin-turbocharged "Hurricane" I6 will offer V8 power, forced induction torque and six-cylinder efficiency in a package designed to fit into any of the company's North American rear-wheel-drive platforms.  What is "V8 power," exactly? Well, in standard output guise, the new I6 cranks out more than 400 horsepower (the specific figure will vary by application) and 450 pound-feet of torque, while the high-output variant is good for more than 500 horses and 475 lb-ft. The final figures will be dependent on the application. We'll save you a little legwork: In current Ram, Jeep and Dodge products, the 5.7-liter Hemi tops out at about 395 hp and 410 lb-ft, give or take, and the 6.4-liter around 485 hp and 475 lb-ft.    This is a clean-sheet design that is only related to the company's turbocharged four-cylinder by some common measurements. The I6 is exclusively direct-injection (no hybrid/port-injection here) and the two I6 variants share 96 common parts, including the block and oil pan design. The differences are found in their internals, intake plumbing, valvetrain components and the turbochargers themselves. Stellantis is not yet ready to share specs or supplier info for the turbos but says announcements will come from its partners soon.  The standard-output I6 has a compression ratio of 10.4:1 and revs to 5,800 rpm. It will run on regular fuel, albeit with reduced performance; 91 octane is recommended for maximum output. The high-output variant has a compression ratio of 9.4:1 and will rev to 6,100 rpm. That one will require premium. The new I6's advantages go beyond basic power output. Every Hemi family engine currently in production is based on an iron block design, so they're heavy. The aluminum-block I6 shaves weight off the total engine package, even if some of that gets added back thanks to the turbos and their associated plumbing. The standard-output I6 weighs 430 pounds, Stellantis engineers told us; the high-output adds just another 11. Fully dressed 5.7-liter V8s are in the 550-560-pound ballpark, and 6.4-liters close in on 600 pounds.  You may be wondering, "Why a clean-sheet gasoline engine now, when the industry is moving toward battery-electrics?" A valid inquiry, and one Stellantis was prepared to address. While the company will be pivoting to electrification over the next decade, it won't be instantaneous.

2014 Jeep Grand Cherokee probed by NHTSA for brake problems

Remember how Toyota got in all kinds of trouble over unintended acceleration? Well, the National Highway Traffic Safety Administration is investigating Jeep over unintended braking. NHTSA has announced a probe of 20,000 Grand Cherokee SUVs from model year 2014. Nine complaints have been received, with owners alleging that their Jeeps have issued brake warnings or gone ahead and applied the brakes when no threat was presented. Each complaint alleges that the vehicles have exhibited this behavior repeatedly, leading to a "sudden reduction in vehicle speed in traffic." So basically, a system designed to prevent accidents could actually increase the odds of a collision happening. Speaking to the Associated Press, Jeep spokesperson Eric Mayne said owners whose vehicles are exhibiting this behavior should report to dealers, while adding that the automatic braking/adaptive cruise control systems can be deactivated. Related Video: Scroll down for the official bulletin on the investigation from NHTSA. Date Investigation Opened: JUN 01, 2015 Date Investigation Closed: Open NHTSA Action Number: PE15021 Component(s): FORWARD COLLISION AVOIDANCE Manufacturer: Chrysler (FCA US LLC) SUMMARY: The Office of Defects Investigation (ODI) has received nine complaints alleging inappropriate activations of the autonomous braking system in model year (MY) 2014 Jeep Grand Cherokee vehicles. All nine reports alleged unexpected braking incidents preceded by collision imminent brake warnings and resulting in sudden reduction in vehicle speed in traffic. Two complaints reported autonomous braking incidents with no objects on the road resulting in rapid increase in brake force and anti-lock braking system (ABS) activations. The complaints alleged experiencing multiple events at different locations and road conditions. A Preliminary Evaluation has been opened to assess the frequency, scope and consequences of the alleged defect. The following VOQ numbers are associated with the issues discussed in this resume: 10543837, 10713629, 10690650, 10663320, 10630362, 10596913, 10533622, 10533524, 10651269.

Best plug-in hybrid cars, SUVs and minivans for 2024

We’re fans of electric vehicles, but they have their shortcomings. TheyÂ’re not available in as wide of a range of body styles as gas-powered cars, and theyÂ’re still limited by range and charging infrastructure. Plug-in hybrids (PHEVs) offer a great compromise, though, allowing for all-electric driving, but also having a gas engine for when you need more power or to travel long distances. Choosing a plug-in hybrid vehicle also allows more options; for instance, you canÂ’t get an all-electric minivan in the U.S. Â… yet. But with those extra PHEV offerings, it might be difficult to know where to start shopping. WeÂ’ve narrowed it down a bit, bringing you the best plug-in hybrids for 2024, as voted on by Autoblog staff, in various segments to help you pick a great PHEV based on your budget and needs. Best luxury plug-in hybrid large/midsize SUV: Volvo XC90 Recharge Despite showing its age, the Volvo XC90 remains an excellent three-row crossover in terms of design, comfort and safety, and the XC90 Recharge plug-in hybrid only improves the formula with both power and efficiency. Interestingly, with the gas motor powering the front axle and the e-motor powering the rear, the XC90 Recharge operates as a rear-wheel-drive car when only using electric power, and front-wheel-drive when only using gas. The powertrain is good for 455 horsepower and 523 pound-feet of torque, with a 5-second 0-60 time. It can travel 32 miles on electricity alone. Runner-up: Porsche Cayenne E-Hybrid   Best mainstream plug-in hybrid large/midsize SUV: Jeep Grand Cherokee 4xe Do you want an American PHEV with style, refinement and off-road capability? The Jeep Grand Cherokee 4xe combines all that with a turbocharged 2.0-liter and electric motor good for 375 horsepower and 470 pound-feet of torque, as well as an electric range of 26 miles. That means you can enjoy your favorite trails in near silence and make fewer trips to the gas pump on the way there. Runner-up: Kia Sorento Plug In-Hybrid   Best luxury plug-in hybrid compact/subcompact SUV: Volvo XC60 Recharge Volvo borrows the formula from the XC90 and places it in a smaller package to get the XC60 Recharge. It has the same 455 horsepower and 523 pound-feet of torque, but it drops the 0-60 time to 4.5 seconds while offering 35 miles of electric range. You can even pony up for the Polestar Engineered trim to get the Ohlins suspension, Brembo brakes, 21-inch forged wheels and unique styling.
